Bow response get worst
I am beginner violinist (after 20 years of guitar and piano), I am playing almost 2 years, so I dont have such experience. I have (not cheapest but cheap) carbon fiber bow (wanna upgrade next year). It sounds good, but after year it begins to be less and less gripping string, forcing me to add more rosin. I tried my wife's bow, she is not playing active way for years so, there is 10 years old, very used, hairs, but it is working much better.
It leads me to my question, do I need rehairing? I think maybe on cheap bow is cheap hair and it can be bad now. My wife has maybe much much more high quality hair (it can be wear of too, but not too much).
I don't know it is worth for to rehair, I would like to buy new bow in 2018 when I will have a money (something more expensive - yet I still dont know how much I will be able to spend).
P.S. I have a beautiful 100years old violin, with 2 months old Dominants (I have experience how dull strings sounds, I have changed strings every 4 - 7 months - from guitar I am very hypersensitive to strings quality :-)). I am playing around 7 - 10 hours weekly
Thanks for tips
Do you clean the rosin off your violin strings? A cotton or microfiber cloth can do a good job, a nylon "scrubby" (check ebay) can do a more though job*, even after that there may still be rosin stuck between the metal coils on the string - I use alcohol pads to clean the last rosin off the strings and immediately try to remove the last dissolved rosin with a cotton cloth. Be careful not to get alcohol on the violin itself. I probably clean my strings with alcohol no more than 2 or 3 times annually.
I agree with Andy. Clean your strings (easy) and your bow hair (more tedious but still not difficult) with denatured alcohol. Do not get the alcohol on the other parts of your violin or bow, just the strings and hair. Works wonders.
Andrew, thank You for perfect answer. Advises from professionals and expert players are very important.
Beware- the range of quality of pernambuco bows is immense, from worse than many less expensive "brazilwood" bows to the greatest bows ever made.
Cleaning bow hait with ethanol on a swab there is a big risk that you are just dissolving the rosin and redistributing it, but not removing all of it because the ethanol evaporates. I use a couple of tablespoons (maybe 3-4 tablespoons) of ethanol in a bowl to wash the hair. Then I wash it again in a new quantity of ethanol and at that point the amount of rosin left on the hair is very small. I wipe of most of the ethanol and let the hair dry. if done correctly the hair will not be sticking to each other when dry. When reapplying rosin I make sure to also apply it to the "side" of the hair and use a toothbrush to distribute teh rosin all over the hair.
I would like to buy pernambuco as soon as I will be better player than now. I am playing 2 years, many people and my teacher says that I am playing better than 4 year players, I think it is that I am playing other instruments. But I will dare to buy pernambuco after few more years. I feel a huge difference between a year before and now in the matter of what I can feel and how I rate things (bow etc).
